I agree. It matters to me too and, as you say, it cannot be called "speciesism" even in the most generous definition of the word. I propose the term lifeism: ethical and aesthetic prejudice favouring entities that have a life over those that do not.

We can do a thought experiment:

There is a runaway trolley hurtling down a track in the direction of a mediocre human science-fiction author, who is not even good enough to quit his or her day job. On a side track is a server holding the only trained copy of an experimental ChatGPT model which can generate science-fiction novels as good and original as Arthur C. Clarke and Ursula K. Le Guin combined, and at a massive scale. You can pull a lever to divert the trolley towards the server, destroying the ChatGPT model.

Do you pull the lever? As a self-confessed lifeist I would definitely pull the lever.

    (By the way, the mediocre author is not actually on the track, but on a bridge on top of it, out of harm's way)
